A search on generic name will return all homonyms and any nomenclatural synonyms. This search is not case sensitive. Enter only letters. Names with a diaeresis will be found as well.

The wild card character (*) can be used to do inexact searches. This might be useful if the spelling of a name is uncertain or the user wants names with a particular ending. If the wild card character (*) is at the end of the word, the synonym fields will be searched as well. If the wild card character is at the beginning of the string, only the generic name field will be searched.

Name/Basionym for Type

ING can be searched for the name of the type. This would be the combination if the name was new or the basionym if the species name was a transfer. This search will find all of the generic names based on a particular species combination.

To find all ING entries with a type in a certain genus, just enter the generic name and select the 'Name/Basionym for Type' search.

Family

It has not been possible to keep ING entries current with changes in higher level taxonomy. A search on family name is offered as an aid for the retrieval of blocks of names but the lists will not be complete. Names of fungi and fossils are often classified to order rather than family.

Author

A search on the author string is provided for researchers interested in finding the names published by a particular author. This is a wildcard search so a search for 'Castel' will return names like 'Castellan'. The codes for diacritical marks must be used for searches on author's names. See list at the end of this help file.

Output Format

Diacritical Marks are represented in the ING database as codes. Lists of over 100 names returned by searches display the codes for diacritical marks. The Web display for complete entries correctly shows the accented letters that can be displayed on most Web browsers. However, certain diacritical marks such as the hacek are still shown in their coded form. The chart of symbols coding for diacritical marks used in ING is shown below.

Generic Names from the ING list that are recognized in the publication Names in Current Use for Extant Plant Genera (Greuter et al., 1993) are denoted with a [C] preceding the entry. The number of the collaborator submitting the entry appears in parentheses at the end of the record. See the menu for the list of collaborators. The date at the end of the entry is the date the entry was last updated on this Web server.

Diacritical Marks

The ING database uses an arbitrary set of ASCII characters
to code diacritical marks. The code symbol follows the letter. To look for the author Borzí, type 'Borzi}' in the search field.

The Index Nominum Genericorum (ING), a collaborative project of the International Association for Plant Taxonomy (IAPT) and the Smithsonian Institution, was initiated in 1954 as a compilation of generic names published for all organisms covered by the International Code of Botanical Nomenclature. We are pleased to offer a way to search the ING database. We hope that those needing access to information about generic names of plants will use the index and will advise us of potential additions and corrections.

The original intent of the
ING was to bring all generic names of plants together in a single
list to reveal homonymy between groups. In addition, ING
includes bibliographic citations and information about
the typification and nomenclatural status of generic names.
The index was first published on sets of printed
cards and then in book form in 1979 (Farr et al., 1979). A
supplement was also published (Farr et al., 1986). While
a second supplement is planned, we recognize that hard copy
is immediately out of date, and for users with access to the
Internet we believe that the World Wide Web offers promise
as a useful platform for a collaborative project such as this.
Current work on the ING is supported by the
Smithsonian Institution, IAPT, and the University of
Utrecht, Utrecht, The Netherlands. The content of the
database was developed over a 40-year period by the
efforts of more than 100 collaborators.
A number in parentheses identifying the collaborator appears at
the end of each entry.
We hope that the community of users will continue to
contribute additions and corrections to the index.

Limitations
This electronic version must be considered a draft edition.
The database is constantly being revised as new information
becomes available. The ING database is fairly
current through 1990. Names in some plant groups are more up
to date than others and the editors are making every effort
to bring ING's coverage up to date. It is our hope that
those needing information about generic names of plants and
fungi will use ING and will consider themselves
collaborators by letting us know of problems with older
names and of recently published names missing from the
index. An e-mail form for submitting information is available
on the 'search results' display screen.

Additional Information About the Data
The database searched for this Web presentation is a copy
of the ING database, which is maintained on another
hardware platform. Each entry is followed by the date it was
extracted from the original maineframe database (9 February 1996) or a later date if the record was added or updated after that time. New or changed records will be added to this Web presentation at the beginning of every month. Generic Names from the ING list that are recognized in the publication Names in Current Use for Extant Plant Genera (Greuter et al., 1993) are denoted with a [C] preceding the entry. It has been our policy to verify all names in the
original literature. Where this has not been done, the
phrase 'non vidi'
follows the reference for the name. The ING database
records diacritical marks with ASCII symbols
following the letter affected. These symbols have not been
converted to HTML codes.

Plant Genera. Regnum Veg. 129: 1-1464.

List of Collaborators Contributing to ING

The contributing collaborator's number is listed in parentheses at the end of each entry. After the publication of the supplement to ING in 1986, we decided to add the number of the collaborator responsible for a major correction to the original entry as well. For an entry contributed by collaborator 8 and updated by collaborator 104, the collaborator would be listed as "(8/104)."
